Ending in -ippa

A Roman forename, and later family name, used for both sexes in ancient times (but more commonly men).

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.

Pippa, a peppy condensation of Philippa that turns it from serious to sprightly, has come into the public eye in a big way via the former Kate Middleton's sister.
